A new research paper introduces a compact screw-based pellet extruder for high content feedstocks, and it could materially shift costs and throughput for polymer, metal and ceramic additive ...

However, industrial 3D printing machines differ greatly from traditional desktop printers. Besides the format of the machines and the prints, one major difference can be found in the material that is ...

Extruders are devices that heat and melt the feedstock and extrude it through the nozzle along a predetermined path on the print bed. Based on the material feeding, 3D printers are classified as ...

When you want to build a large format 3D printer, you can’t just scale up the design of a desktop machine. In an excellent four-part build series (videos after the break), [Dr. D-Flo] takes us through ...

Researchers mapped how material composition changes during switchovers in large format, pellet-fed 3D printing.

A Geelong start-up has developed a system that adapts commercial 3D printers to use pellets made from recycled materials such as crushed plastic as its printing feedstock. Created by Polylab, the ...

Pellet extrusion is under increasing pressure to reduce energy use and material waste while maintaining consistent pellet ...

The authors compare three systems of single-screw extrusion using binary formulations for their suitability for producing pellets of various formulations and under various spheronization conditions.

Here’s the situation: a kilogram of 3D printer filament costs about $50. A kilogram of plastic pellets costs less than a tenth of that. Does anyone have a solution to this problem? For years now, the ...
